the forward' thrust and` return movement of t'he'follower. v

Another object ofl the invention is the provision of a cuc cliallzer of simple and attractive design, cheaply manufactured, of' economical operation, and ofi character thatwill'preventy layers:inadvertently carrying offthe chal t.Y v

Other" objects and advantages-will appear with reference to the subjoined" specification and accompanying.: one sheet of drawings, in which z Figurey 1` is perspectiveI .view` ofiy my cuechalker, as it wouldV appear attached" to a supl'iorting'objectf in readinessforuse, the barrel being zuljustable-to anyangle, rela#` tive `to Athe supporting bracket;

Figure'Z is a'longitudinal'mlddsection of tl'ied'evice, showing'theispri'ng and follower in normal4 position and thechalk inireadlness'for use, the section being taken as indicate'dVby the line 2 2 ofFigure 3,

Figure 3 a fragmtintary end view` of' thef device', showing t-'lief method` of rifiin'g the" barrel, andv the i corresponding proj ections formed'upon the periphery ofthe fol'- lower,` l i y Figure l-is a perspective viewot' thefol lower, showing the chalk-gripping recess formed in?i the' outer endl thereof; and the spirally arranged projections carriedtl'iereby and adapted to travelin the barrel rifling to cause the partial rotation' of the follower when thrust into or retracted in the barrel; and

Figure 5 is a sectional detail of thesupporting lug and hinge-ears cairied by the barrel, both being provided with serrations upon their contacting faces to rigidly hold the barrel at any desired angle relative to the supporting bracket.

Referring with greater partieularity to thedrawings, l-desig-natesfthe barrel of the device, ywhich is preferably die-cast ofwalummum or other light metal, the `barrel bein'g provided with ay finished bore 2, op'enl at its outer end and closed at its inner end 3: The outer end of the barrel'is exteriorly screw-threaded, as indicated at l, and provided with an interiorly screw-threadedleap 5, said cap being provided with: an inwardly? extending lip 6, concentrica-lly disposed relative to 'the barrel and cap,` and a centrally` disposed. outwardly flaredv opening 7 adapted to'receive and guide the cue tip tofthe chalk 8 which is held spring-seated upon the lip 'G within the barrel" end.

A follower 9 provided having'. an exterior diameter slightly smaller thanl that of the ybore '2 of the-barrel7 adapting it to form a sliding lit therein, the inner eudof thel follower being recessed, indicated at f 10,-and provided witlra centrally positioned member l1 upon'which af bearing'waslu-fr 12 is seated, said washer-beingadapted to providei' a bearing for' the expansion spring 13', providing: a means againstwhichf the fol# t lower member' 9 may rotate when forced longitudinally, in either directioinalong the barrel. v

The spring' 13'is seated'in'thereccss l() oft'h'e followerand'isv of somewhat smaller diameter than that of theharrelbore 2 an'd extendsv betwecw thel washer 121 and upper endy 3 ofthe b'arrelgtle springurgc tendingl to" normally hold thefol'lowcr iir the outerf end of the" barrel,- with' f the chalk Si sca-ted upon the lip 6 of' the cap' as shownin; Figure 2.'

The'bore 2 of the barrel is groored, or riied, fromits outer end rearwardly,l the ri'fling eXtendinga approximately half the lengthv of thebarrel, with the rifles,- or giifooves', 14: ancll arranged" in diametrical opposition; Eigures y2' and 3,/and in re= versed" spiral directions, as shown -iniligure 2;

The follower 9'is provided with periph; erally arranged and diametrically"disposed lugs 16 and 17 extending spirally thereabout in reversed order and of a depth and form to fit loosely in the grooves 14 and 15 of the barrel, in which they are adapted .to travel and, therethrough, rotate the fol lower 9, a thrust inwardly to the limit of travel accomplishing, approximately, a onehalf rotation of this chalk-bearing member.

A spirally arranged groove 18 is formed in the outer surface of the follower and terminates adjacent the inner end thereof, said groove corresponding in pitch to that of the groove liJf and adapted to prevent the complete ejectment of the follower` through engagement with a small screw 1Q` tapped into the barrel wall and extending into the bore of the barrel far enough to engage in the groove 1S, but not to a sufficient depth to prevent the complete rotative action of the follower.

Normally the follower' is held slightly within the end of the barrel by the cue chalk 8. which is held seated upon the lip G of the cap by the spring 125. Vlhen necessary lo insert a new piece ofchalk in the follower, the cap is removed, the follower being held from ejectment by the screw 19 engaging the inner end of the groove 1S. The outer end of the follower is provided with a rectangular recess 2O of sufficient size to accommodate the ordinary cube form of rhalk, but` that it ,may also acconunodatc that of cylindrical forni` arcuate sections are removed from the sides of the said reeess as represented by 21, Figure 4f, these Ylrfatures contributing to the prevention of ro* tation of the chalk in the follower.

rlhe barrel is provided at its .inner end with integrally formed hinge-ears 22 and 23 adapted to embrace a sinliporting lug 24 integrally formed with a supporting plate 9,5.v the said ears and lug bearing openings adapted to accommodate a hinge bolt 26 having a head at one end and a nut 27 adapted to be drawn up tightly to set and retain the barrel l at any desired angle relative to the supporting plate,` the inner faces of the hinge-ears and the outer faces of the lug 24 being correspondingly serrated, as indicated at QS and 29. as interlockingaids to permancy of position of the barrel, once these members have been tightly drawn together by setting` up the nut 27. The supporting plate may be properly secured in any convenient position by means of screws 30 and 231, The member 1l of the follower and the end 3 of the barrel are provided with perforationf-f 32 and 33, as means affording relief against air-pressure.

The outer face of the member l1, against which the chalk S rests, is provided with a plurality of radially extending ribs 34, adapted to assist in holding the chalk against tendency to rotate, relative to the follower 9.

Having thus described my inyention, l claim, and desire to secure by Letters Patent:

l. A billiard-cue chalker comprising a barrel, a supporting bracket therefor comprising a. member adapted for hinged connection to said barrel, a bore extending longitudinally of said barrel and provided with a pair of reversely arranged rifles or grooves and of diametrically opposite disposition, a follower adaptcd for longitudinal and rotary movement in said barrel bore and provided with peripherally placed lugs adapted to it and travel in said grooves.` a spring in said bore between the inner end of the barrel and said follower and adapted to normally hold said follower in the outer end of the barrel bore, a recess in the outer end of the follower adapted to hold a piece of cue chalk, a peripheral groove carried by said follower adapted to engage a screw borne by the barrel wall for preventing the complete ejectment of said follower from the barrel bore-` and means for normally holding said follower and chalk slightly within the end of the end of the barrel bore.

2. A billiard-cue chalker comprising in combination, a supporting bracket, a barrel hingedly secured to said bracket and adapt ed for angular' adjustment relative thereto.` a retaining cap having a flared opening` and lip secured to the outer end of said barrel, a bore extending longitudinally of said barrel and provided with a pair of reversely arranged spiral rifles or grooves of diametrically opposed disposition, a follower adapted for longitudinal and rotary movement in said barrel bore and provided with peripherally arranged lugs adapted to fit and travel in said grooves, a spring in the barrel bore between the follower and the inner end of the barrel and adapted to urge said follower toward the open end of the barrel, a. chalk recess in said follower adapted to grip and hold the chalk, said spring acting to normally hold the chalk seated against said retaining cap-lip in position for use` and a peripheral groove carried by said follower and adapted to engage means projecting inwardly from the barrel wall for preventing the complete ejectment of said follower from the barrel bore.

In testimony whereof I have aflixed my signature.

ARTHUR R. PETERSON.
